How does one find the percent uncertainty in the volume of a sphere whose radius is r equals 1point56 plus or minus 0point05 meters?
-- Find the volume of a sphere with radius = 1.56 -- Find the volume of a sphere with radius = 1.61 -- The uncertainty is the difference between the bigger result and the smaller one. -- For the percent uncertainty, find out what percent that difference is of the (r = 1.56) volume. (Divide the difference of the two volumes by the volume you get with r=1.56 . Multiply the result of the division by 100, and you have the percent of uncertainty.) (Just knocking it out quickly on our calculator, we get about 9.93% uncertainty. This may or may not be correct, and you should not depend on it. But if you get the same answer, then we're probably both right.) Here's an important tool that you'll need to do this job: Volume of a sphere = 4/3 (pi) (radius)3
What does 12 plus 30 percent minus 15 percent plus 40 percent equal?
12 x (1 + (30/100)) = 15.6 x (1 - (15/100)) = 13.26 x (1 + (40/100)) = 18.564
What is x if x minus 20 percent of x equals y?
x is y plus 25% of y.
What is purple minus red plus yellow minus blue plus red minus yellow plus blue?
Purple.
What symbols do you use?
plus sign (+), minus (-), number (#), decimal point for decimals and money, percent (%), dollar sign ($), equal (=)
What is a zero error in an instrument?
This is actually impossible, even for machines, but a zero error would mean there is no uncertainty in the measurement, as in no possibly plus or minus a unit.
What is the uncertainty of an analytical balance?
The uncertainty value of any measurement instrument is half of it's smallest unit it measures. for example, a graduated cylinders measures by half mL, so the uncertainty would be plus or minus .25 g
What symbol expresses uncertainty in a measurement?
All measurements are 'wrong', so we note how good our measurement technique is by providing a range either side of the measured value. Typically it's the plus-minus symbol ±, e.g. 35.8±0.4 kg. The greek lower case sigma is used in mathematical notation to represent uncertainty: σ.
100 percent minus 50 percent plus 300 percent is what answer?
350 percent
What is 1 minus 35 percent plus 25 percent?
0.8125
When you calculate percent error you can ignore the?
Plus and Minus Signs

What can you ignore when you calculate percent error?
plus and minus signs
When you calculate percent error you ignore what?
